Flutter Text Widget

In Flutter the Text widget is used to display single or multi-line string in UI. If we don’t specify any styling in a text widget, it will use DefaultTextStyle.

In this tutorial, you will learn how to efficiently use the Text widget and how to style the text widget using the style property. Here a simple example of Text Widget.

Text("This is a Text Widget"),
Code language: JavaScript (javascript)

When we run this code, we will get output like this,

Flutter Text Widget Line Break

If you have multiline text, to break the text at specific word use \n escape character. For example,

Text("This is a Text Widget \n by Code With Flutter"),
Code language: JavaScript (javascript)

Flutter Text Overflow

Sometimes text overflowed because of not specifying the width of the widget. To solve the text-overflow problem, use the overflow property. Here an example of overflow property.

Text( "When using long text, sometimes text overflowed some pixels. To sole this", <strong>overflow: TextOverflow.ellipsis,</strong> ),
Code language: HTML, XML (xml)

Using the overflow: TextOverflow.ellipsis property, it will append three dots at end of the text. Here is an output of the code.
